I ask myself does what I'm watching gives glory to God, if it doesn't it is of the world. The world is satanic. It is apart of the cosmos system where satan rules in this present time. Anime is of the world (for the most part from my 100's of series watched). I watch anime, some I can't because its too blatant in being worship of the worldly things that give no glory to God. I can still appreciate the imagination and skill put into a show. You can find things that are beautiful results of Gods creation but are tainted by our sin nature. A litmus test would be would you take show "x" into a youth group or congregation and it give glory to God. I havent found one. If it hurts to hear that don't shot the messenger. However far you want to dive into anime and how much you enjoy it is up to you and you alone. I don't care how much importance you put into anime, I have my own sin nature that I put things in to high a priority in my life. At the same time you can't convince me that it brings glory to God and anime fits into place the Bible shows it doesn't. This doesn't just apply to anime as I just alluded to. This just the topic of this post so I'm keeping it to anime but insert any topic, porn, narcissism, unrighteous pride, "living your best life", and the list goes on. I don't let my opinions of the person saying things dictate the facts or lies someone says. I don't like matt walsh but there is nothing in the Bible that even alludes to anime (for the most part) being anything close to giving glory to God and something I should have hold any spiritual weight in my life when the themes are sexual, demonic, pedophilic, atheistic, and pagan.
